Add within 10 Change-Unknown & Start-Unknown 1-18

Use ten frames to find an unknown part in an addition equation. 5 + __ = 7? Visualize 5 on a ten frame – a full top row. Now imagine 7 – a full top row and 2 more. What's the "change" – how many need to be added to 5 to make 7? Since 5+2 = 7, the part needing to be added is 2. Draw to check for accuracy.
